A computer is programmed to identify first and second regions of an image representing a seatbelt, actuate an output device to deliver a first output upon detecting an absence of the seatbelt in the first region and in the second region, and actuate the output device to deliver a second output upon detecting an absence of the seatbelt in the first region and a presence of the seatbelt in the second region.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A system comprising a computer, the computer programmed to: identify first and second regions of a seatbelt image; actuate an output device to deliver a first output upon detecting an absence of a seatbelt in the first region and in the second region; and actuate the output device to deliver a second output upon detecting an absence of the seatbelt in the first region and a presence of the seatbelt in the second region.
2. The system of claim 1 , the computer further programmed to: actuate the output device to deliver the first output upon detecting an occupant in the image, an absence of the seatbelt in the first region, and an absence of the seatbelt in the second region; and actuate the output device to deliver the second output upon detecting the occupant in the image, an absence of the seatbelt in the first region, and a presence of the seatbelt in the second region.
3. The system of claim 1 , the computer further programmed to select a location in the image for the first region at a chest of an occupant.
4. The system of claim 1 , the computer further programmed to select a location in the image for the second region above a shoulder and beside a head or neck of an occupant.
5. The system of claim 1 , the computer further programmed to actuate the output device to deliver a third output upon determining that an occupant is inattentive.
6. The system of claim 1 , wherein the first region is located in the image where a chest of an occupant of 50th-percentile stature sitting in a seat is expected to be located.
7. The system of claim 1 , wherein the second region is located in the image above where a shoulder and beside where a head or neck of an occupant of 50th-percentile stature sitting in the seat is expected to be located.
8. The system of claim 1 , wherein the first output includes a first actuation of a user interface and a limitation of vehicle speed, and the second output includes a second actuation of the user interface and a limitation of vehicle speed.
9. A method comprising: identifying first and second regions of a seatbelt image; actuating an output device to deliver a first output upon detecting an absence of a seatbelt in the first region and in the second region; and actuating the output device to deliver a second output upon detecting an absence of the seatbelt in the first region and a presence of the seatbelt in the second region.
10. The method of claim 9 , further comprising: actuating the output device to deliver the first output upon detecting an occupant in the image, an absence of the seatbelt in the first region, and an absence of the seatbelt in the second region; and actuating the output device to deliver the second output upon detecting the occupant in the image, an absence of the seatbelt in the first region, and a presence of the seatbelt in the second region.
11. The method of claim 9 , further comprising selecting a location in the image for the first region at a chest of an occupant.
12. The method of claim 9 , further comprising selecting a location in the image for the second region above a shoulder and beside a head or neck of an occupant.
13. The method of claim 9 , further comprising actuating the output device to deliver a third output upon determining that an occupant is inattentive.
14. The method of claim 9 , wherein the first region is located in the image where a chest of an occupant of 50th-percentile stature sitting in a seat is expected to be located.
15. The method of claim 9 , wherein the second region is located in the image above where a shoulder and beside where a head or neck of an occupant of 50th-percentile stature sitting in the seat is expected to be located.
16. The method of claim 9 , wherein the first output includes a first actuation of a user interface and a limitation of vehicle speed, and the second output includes a second actuation of the user interface and a limitation of vehicle speed.
17. A vehicle comprising: a seat; a camera aimed at the seat; and a computer in communication with the camera and programmed to identify first and second regions of a seatbelt image from the camera; actuate an output device to deliver a first output upon detecting an absence of a seatbelt in the first region and in the second region; and actuate the output device to deliver a second output upon detecting an absence of the seatbelt in the first region and a presence of the seatbelt in the second region.
18. The vehicle of claim 17 , wherein the computer is further programmed to select a location in the image for the first region at a chest of an occupant and to select a location in the image for the second region above a shoulder and beside a head or neck of the occupant.
19. The vehicle of claim 17 , wherein the first region is located in the image where a chest of an occupant of 50th-percentile stature sitting in the seat is expected to be located, and the second region is located in the image above where a shoulder and beside where a head or neck of an occupant of 50th-percentile stature sitting in the seat is expected to be located.
20. The vehicle of claim 17 , wherein the first output includes a first actuation of a user interface and a limitation of vehicle speed, and the second output includes a second actuation of the user interface and a limitation of vehicle speed.
